Steps to Calculate GCD of 481, 420, 272, 790 using LCM Formula

Given numbers are 481, 420, 272, 790

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(481, 420) = 202020

GCD(481, 420) = ( 481 x 420 ) / 202020

= 481 / 420

= 481


Step2:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1


Step3:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1


So, Greatest Common Divisor of 481, 420, 272, 790 is 1
